DETAILED DESCRIPTION
[0024] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0025] Reference Figure 1-Figure 6As shown, the utility model provides a pre-treatment warp feeding device for a warp knitting machine for preparing cool fabrics, including a frame 1, and a warp feeding mechanism 11 for conveying warp threads is arranged on one side of the top of the frame 1. The main function of the warp feeding mechanism 11 is to convey the warp threads and ensure that the warp threads can enter the subsequent processing flow in an orderly and stable manner. A cleaning device 12 for cleaning the warp threads is arranged on one side of the top of the frame 1 away from the warp feeding mechanism 11. The cleaning device 12 removes stains and impurities on the surface of the warp threads to ensure the quality of the fabric. A drying device 13 for drying the warp threads is arranged on one side of the cleaning device 12. An adjusting device 14 for adjusting the tightness of the warp threads is arranged on one side of the frame 1 close to the warp feeding mechanism 11. The adjusting device 14 includes a tensioning mechanism 143 that can independently control the tightness of each warp thread. The tensioning mechanism 143 has the ability to independently control the tightness of each warp thread. By adjusting the tensioning mechanism 143, the tightness of each warp thread can be accurately adjusted, thereby ensuring the stability and uniformity of the warp threads during the weaving process.
[0026] The adjusting device 14 includes a support plate 144 fixed on the frame 1, and a tensioning mechanism 143 is arranged in several groups on the support plate 144. The tensioning mechanism 143 includes a connecting block 1431 fixed on the top of the support plate 144, a wheel frame 1432 is rotatably arranged on the connecting block 1431, and a tensioning wheel 1433 is rotatably arranged on the top of the wheel frame 1432. The tensioning mechanism 143 also includes a driving mechanism for driving the wheel frame 1432 to rotate.
[0027] The driving mechanism includes a second transmission rod 1436 movably connected to the wheel frame 1432, and the driving mechanism includes a first transmission rod 1435 rotatably set on the support plate 144, and the cross-sectional shape of the first transmission rod 1435 is a "V" shape. The driving mechanism also includes a telescopic driving member 1434 movably set on the frame 1, and the output end of the telescopic driving member 1434 is movably connected to one end of the first transmission rod 1435 through an axis, and the other end of the first transmission rod 1435 is movably connected to one end of the second transmission rod 1436.
[0028] The adjusting device 14 includes a first guide roller 141 and a second guide roller 142. The first guide roller 141 is rotatably arranged on the frame 1 near the warp feeding mechanism 11, and the second guide roller 142 is arranged on the frame 1 near the drying device 13. Through the driving action of the telescopic driving member 1434 and the transmission action of the first transmission rod 1435 and the second transmission rod 1436, the wheel frame 1432 is driven to rotate, and the position of the tensioning wheel 1433 is adjusted to achieve precise control of the tightness of the warp.
[0029] The wheel frame 1432 is swung around the axis between the wheel frame 1432 and the connecting block 1431 through the driving mechanism, thereby adjusting the position of the tensioning wheel 1433. The tightness of the warp is adjusted by changing the distance between the tensioning wheel 1433, the second guide roller 142 and the first guide roller 141. The tension of each warp can be adjusted independently, which solves the problem that the traditional method of adjusting multiple warps at the same time causes the overly loose warp to become tight, while the overly tight warp will be broken.
[0030] The second guide roller 142 is installed at a height higher than the tension wheel 1433 , and the first guide roller 141 is installed at a height lower than the tension wheel 1433 .
[0031] The warp feeding mechanism 11 includes a rotating shaft 112 rotatably arranged on the frame 1, and a plurality of warp feeding wheels 113 are evenly distributed on the rotating shaft 112. The warp feeding mechanism 11 includes a rotating driving member 111 installed on the side of the frame 1, and the output end of the rotating driving member 111 is drivingly connected to the rotating shaft 112.
[0032] The telescopic driving member 1434 can automatically rotate the first transmission rod 1435, and the first transmission rod 1435 rotates the second transmission rod 1436, thereby rotating the wheel frame 1432, thereby changing the position of the tensioning wheel 1433, thereby realizing the automatic adjustment of the tightness of the warp.
[0033] refer to Figure 3 and Figure 4 As shown, the cleaning device 12 includes a water tank 121 fixed on the frame 1. The water tank 121 is the main part of the cleaning device 12. The water tank 121 is fixed on the frame 1 and is designed with through grooves on both sides. These through grooves allow the warp to pass through the water tank 121 smoothly without being blocked. Through grooves for the warp to pass through are opened on both sides of the water tank 121. A diverter 124 is fixed on the top of the water tank 121. A nozzle 1241 for spraying water is arranged at the bottom of the diverter 124. The cleaning device 12 also includes a pump body 122 arranged inside the water tank 121. The water outlet end of the pump body 122 is connected to a connecting pipe 123. One end of the connecting pipe 123 is connected to the diverter 124. A filter screen for filtering water is also arranged inside the water tank 121. The main function of the filter screen is to filter impurities and particulate matter in the water to prevent impurities and particulate matter from entering the nozzle 1241 with the water flow and adhering to the warp. This not only improves the cleaning effect, but also extends the service life of the nozzle 1241.
[0034] When the cleaning device 12 is working, the pump body 122 starts to pump water and transmits the water to the diverter 124 through the connecting pipe 123. The diverter 124 evenly distributes the water flow to each nozzle 1241, and the nozzle 1241 sprays the water onto the passing warp. In the process of passing through the water tank 121, the warp is continuously flushed and cleaned by the water flow, thereby removing stains and impurities on the surface. At the same time, the filter screen continuously filters the water quality inside the water tank 121 to ensure the stability and efficiency of the cleaning process.
[0035] Working principle: When the device is used, it is first installed on the warp knitting machine. Then, the warp is wound around the first guide roller 141, the second guide roller 142, the tensioning wheel 1433 and the warp let-off wheel 113. The movement and transmission of the warp is realized by the driving action of the warp let-off wheel 113 and the coordinated rotation with the winding wheel on the warp knitting machine. During the movement of the warp, if the warp becomes loose, it may affect its normal transmission. At this time, the telescopic drive member 1434 is started, and the telescopic drive member 1434 drives the first transmission rod 1435 to rotate, thereby driving the second transmission rod 1436 to rotate. This linkage mechanism ultimately causes the wheel frame 1432 to drive the tensioning wheel 1433 to rotate. By accurately adjusting the relative positions between the tensioning wheel 1433, the first guide roller 141 and the second guide roller 142, the tightness of the warp can be effectively adjusted. In addition, the tension of each warp can be adjusted independently, thus solving the problem of uneven tightness caused by adjusting multiple warps at the same time in the traditional method, and avoiding the phenomenon that too loose warps become tight or too tight warps are broken. When the warp is in motion, the pump body 122 is started, and the pump body 122 pumps water into the diverter 124. Then, the water is evenly sprayed out from the diverter 124, directly acting on the warp, to effectively clean the dust on the warp. After cleaning, the drying device 13 is started to dry the warp in time.
[0036] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
